Your mission is:• Pair up – or jump in a 3, or do this individually – your choice (tryyour best to pair up)• You will have a timer between you to share.• 1. One person will time, the other will walk/run 100m• When finished, record the time you took to run/walk.• 2. Swap – the timer will now run 100m, the runner will now time.• Make sure to record the time it took you to run/walk 100m!• We will come back up here and calculate our speed!
Speed can be measured in:•Kilometres per hour (km/h)•Metres per second (m/s)
Question•Daisha drove hercar 70km at anaverage speed of35km/h – Howlong was thejourney?Distance = 70kmSpeed = 35 km/h• Time = distance ÷ speed• Time = 70 ÷ 35• Time = 2• We have used the unit“kilometres per hour” so ouranswer is 2 hours
Question• John missed thebus to had to walkhome from school.It took him 2 hours.His average speedwas 6km/h – howfar away fromschool does Johnlive?Speed = 6km/hTime= 2 hours• Distance = speed x time• Distance = 6km/h x 2 hours• Distance = 6 x 2• = 12 kilometres
Question•Kritesh ran 100min 9.58seconds, whatwas his averagespeed?Distance = 100mTime= 9.58 seconds• Speed = distance ÷ time• Speed = 100 ÷ 9.58• Speed = 10.43• So Kritesh was travelling at10.43 meters per second(m/s)
